Average daily sleep maintenance efficiency in all days from actigraphy
avgmainteff5 under Sleep Monitoring/Actigraphy in MESA variables
Sleep maintenance efficiency is the ratio between sleep duration (i.e. total sleep time, tst) and sleep period in main sleep. Sleep duration is the interval between sleep onset time and sleep offset time while asleep, while sleep period is the interval between sleep onset time and sleep offset time.
Average daily sleep maintenance efficiency in non-workdays from actigraphy
avgmainteffnw5 under Sleep Monitoring/Actigraphy in MESA variables
Sleep maintenance efficiency is the ratio between sleep duration (i.e. total sleep time, tst) and sleep period in main sleep. Sleep duration is the interval between sleep onset time and sleep offset time while asleep, while sleep period is the interval between sleep onset time and sleep offset time.
